New Version of UNI EN ISO 5179:2023

Investigation of Brazing Behavior with Wetting and Gap Filling Tests

Improvements and updates

The recent publication of UNI EN ISO 5179:2023 marks a significant advancement in the field of brazing, providing clear and updated guidelines for evaluating the behavior of materials subjected to this critical process.

This standard introduces three specific test methods to verify brazing behavior, offering a comprehensive framework for assessing the effectiveness and reliability of brazed joints.

Wetting Test: This method involves measuring the wetting area of the filler metals during the brazing process. Measuring the wetting area provides crucial information about the ability of the filler metal to melt and spread across the surface of the base material, ensuring effective brazing and strong adhesion between materials.

T-Joint Test: This part of the standard provides a detailed scheme for constructing a T-joint using test samples and a specific test method. This method allows for the assessment of the strength and structural integrity of brazed joints under simulated conditions, providing a reliable indication of brazed joint performance.

Gap Variation Test: This part of the standard describes a test specimen and a test method to evaluate the influence of various parameters that can affect brazing during fabrication based on distances. This method is essential for understanding and optimizing brazing parameters to ensure consistent and high-quality results.

In conclusion, the publication of UNI EN ISO 5179:2023 represents an important contribution to the field of brazing, providing industry professionals with a series of standardized test methods to accurately evaluate the behavior of brazed materials.

These methods will help ensure the quality and reliability of brazed joints, contributing to improved performance and durability of brazed products and components.
